Packaging, temperature regime and documentation all affect whether material arrives in the condition it was released in — and whether it can be booked in without a query.
Lyophilized material is normally supplied in a sealed vial with desiccant and a protective outer package. The vial format should match the quantity and the receiving laboratory’s handling procedure; a format that does not fit the laboratory’s aliquotting process will cause avoidable waste.
Three regimes are used, and the right choice depends on the material specification and the destination climate rather than on a default.
The dispatch note records the packaging type, desiccant, insulation and temperature regime used. This matters at goods-in review, where a reviewer needs to confirm that the agreed shipping conditions were actually applied.
Requirements differ substantially by jurisdiction, and in some countries specific documentation or licensing is required before certain materials may be imported. Buyers are responsible for confirming the requirements that apply to them.
Report the discrepancy with the lot number, the condition on receipt and any supporting evidence such as photographs or temperature records. The case is reviewed against the retained sample and batch records, and the outcome is confirmed in writing.
A Certificate of Analysis is the starting point, not the whole file. This note sets out the documents worth requesting and the point at which to request them.
Purity and identity figures are only meaningful alongside the method that produced them. This note covers how the values are generated and what to check.

Send the catalogue reference or target sequence, required purity, quantity and destination. The procurement desk returns a formal quotation with the documentation package and lead time.
